IGNITING Application filed May 16, 1913, Serial No. 768,035.

To all whom it may concern:

Be it known that I, FRANK L. VAN DUSEN, a citizen of the United States of America, and a resident of the village of Fort Erie,- Ontario, Canada, have invented certain new and useful Improvements in Igniting Devices, of which the following is a full, clear, and exact description.

My invention relates generally to igniting devices and more articularly to devices which produce ignltion by the frictional contact of two metals.

The principal object of my invention has been to provide a device which may be applied to lamps, gas burners and the like for automatically lighting the same.

Another object has been to provide a device which shall be simple to operate and inexpensive to manufacture.

Reference is to be had to the accompanying drawings forming part of this specification, in which I show my invention as applied to an oil burner and in which like characters of reference indicate like parts, throughout the several views of which:

Figure 1 is a plan View of my device with a portion of the base of the burner broken away. Fig. 2 is a side elevation of the same, partly broken away in section on llne 22 of Fig. 1. Fig. 3 is a fragmentary sectional view taken on line 3-3 of Fig. 1.

In the drawings, 5 represents the oil burner of an ordinary lantern; 6 the fuel receptacle for the same which is carried by the usual base 7. The burner 5 is provlded with the usual wick tube 8 and Wick raiser 9.

The spark in my device is produced by the friction wheel 10 against which is frictionally held, a piece of pyrophorous metal 12. The wheel 10 is carried by a shaft 11, mounted to rotate within the oil receptacle 6 of the lantern. This piece of metal 12 is slidably disposed within a sleeve 13 and pressed against the friction wheel 10 by a helical spring 14 disposed within the sleeve 13 and having its outer end bearing agalnst an adjusting screw 15 interiorly screwthreaded to said sleeve. The sleeve 13 is preferably supported upon a standard 16, secured to the top of the fuel receptacle 6. The shaft 11 passes through a sleeve 17 formed within the fuel receptacle 6 and hasdisposed at its lower end a gear pinion 18. Meshing with the gear pinion 18 is a driving gear 19 which is carried at the lower end of the shaft 20 mounted in suitable bear- Speeification of Letters Patent.

ings carried by the lantern parts. Rotatably carried by the shaft 20 and disposed directly over the gear 19 is a ratchet 21, having secured thereto an operating arm 22. The operating arm has secured at its outer end an upwardly extending stem 23 which extends up through a slot (not shown) in the base 7 of the lantern, whereby said arm may be operated. A spring 24 has one end secured to the arm 22 and the other end secured to any suitable portion of the lantern base, whereby the said arm will be retracted and held in its normal position, as shown in the drawings. A ratchet pawl 25 is carried by the operating gear 19 and has its outer end pressed into engagement with the ratchet 21 by means of a suitable spring 26.

A torch 27 is normally disposed within a casing 28 containing some suitable volatile igniting fluid, such as gasolene, or containing some suitable soft packing 29 saturated with the igniting fluid. The casing 28 is located near the wick tube 8 andis preferably provided with spring means disposed beneath the packing 29, whereby the same is always held in contact with the lower end of the torch 27. The lower end of the torch 2.7 has preferably secured thereto a small tuft of asbestos or other non-inflammable material which is always saturated with volatile fluid and is therefore ignited by the sparks coming from the pyrophorous metal, after it has been raised into the ignition field. The torch 27 is provided at its upper end with a member 30 which forms a cover or cap for the casing 28. The torch 27 is rigidly secured to the outer end of a crankshaped arm 31, formed on the inner end of the shaft 32 which has also formed at its outer end a crank-shaped arm 33. At the upper end of the shaft 20 is secured a collar 34 which carries near its periphery a U- shaped member 35. This member engages with the outer end of the crank-shaped arm 33 which is oscillated by said member as the same is rotated by the collar 34:.

When my device is to be operated, the wick of the burner is turned up so that the upper end projects above the tube 8. The ;arm 22 is now rotated by means of the stem 23, thus operating the gear 19 and shaft 20. As the shaft 20 is rotated through a portion of its circumference, the U-shaped member 35 carried by the collar 34 will partially rotate the shaft 32 and raise the torch 27 from the receptacle 28 and carry it into the ignition field. As the gear 19 is rotated the friction wheel 10 will also be rotated through the medium of the gear 18 and shaft 11. The piece of pyrophorous metal 12 contacting with the friction wheel 10 causes a series of sparks to be thrown toward the torch 27, thus igniting the same. When the torch is lighted the wick of the burner will be ignited therefrom. The arm 22 is then released and the spring 24 draws it back to its normal position. At the same time the torch 27 is carried back into the receptacle 28 and the receptacle is closed by the member 30.

Clearly my invention when applied to the oil burner of a lamp or lantern provides a means for lighting the same without removing the globe or chimney surrounding the Wick. Therefore, the ignition of the lamp or lantern cannot be affected by outside drafts of air and can be quickly and with certainty accomplished in any kind of atmospheric conditions without the use of matches.

Obviously, some modifications of the details herein shown and described may be made Without departing from the spirit of my invention or the scope of the appended claims and I do not Wish to be limited to the exact embodiment herein shown and described.
